I don't collect modern paper money, but this item impressed me, as errors on higher denominations are few and far between. It's an eBay image, sorry it's so small. Ebay #332174929783, currently bid to $76, 2+ days left.
Quick tip: you can click on the thumbnail in the listing to show it in the big preview window, then click that to show the full image, then right-click and "copy image URL" (or the equivalent in your browser), then click the "image" icon here and paste it in. You can also take the auction ID number and turn it into an eBay link by putting "http://www.ebay.com/itm/" in front of it, like this: http://www.ebay.com/itm/332174929783 CoinTalk's forum software should automatically turn it into a link.
The note is way off center, especially if compared to the front. It's been my experience that if none of an adjoining note is visible in the margins, then it usually doesn't bring big money.
It is a cool find though, a particular collector may pay a premium however the rest Of us not so much.
